Looks like its been a long time since Korean did some brutal movie like what they always did in the past, especially the one that lead by a woman such as "Bedevilled" (2010) and "Sympathy for Lady Vengeance" (2005). I never read the synopsis, I know that based on the poster it looks like some horror/slasher movie but when the movie starts, Oh! its some gory black comedy, one of Korean best genre that's usually come from Park Chan Wook, one of the South Korean greatest director. So, this movie is an indie movie, a cheap budget one, but honestly, they don't look cheap at all. With a great acting, editing and cinematography whatsoever from a new director, Ahn Gooc-jin. It looks so good, its breathtaking, full of suspense and everything. You don't know what the wife will do for the sake of her beloved husband. Don't underestimate the wife. Its what I learned from this movie. A good brutal movie, enjoy it!
